Using the Equation for Velocity, Acceleration, and Distance Without Time

What does the equation v^2 - u^2 = 2as help us calculate?

• The relationship between velocity, acceleration, and distance

• The time taken for an object to accelerate

• The mass of an object

• The force applied to an object

In the first example, what is the initial velocity of the bus?

• 5 meters per second

• 12 meters per second

• 8 meters per second

• 10 meters per second

How is the acceleration of the bus calculated in the first example?

• By dividing the final velocity by the initial velocity

• By using the equation v^2 - u^2 = 2as

• By subtracting the initial velocity from the final velocity

• By multiplying the distance by the time

In the second example, what is the acceleration of the lorry?

• 1.5 meters per second squared

• 2.0 meters per second squared

• 1.0 meters per second squared

• 0.5 meters per second squared

What is the stopping distance of the motorbike in the third example?

• 200 meters

• 150 meters

• 167 meters

• 180 meters
